Conclusions

  1. 1.

    The influence of pyridine, methanol, ethanol, and allyl alcohol on the rate of decomposition ofπ-allyl palladium chloride in aqueous alkaline solutions, as well as the influence of oxygen on the rate and direction of decomposition of the complex, were investigated.

  2. 2.

    In the presence of pyridine under conditions in whichπ-allyl palladium chloride exists chiefly in the form of the pyridine derivative C3H5PdClNC5H5, practically no decomposition of the complex is observed.

  3. 3.

    Additions of methanol and ethanol lead to a substantial increase in the rate of decomposition of [C3H5PdCl]2. When C2H5OH is replaced by C2D5OH, an isotopic kinetic effect (∼2.8-fold) is observed.

  4. 4.

    Additions of allyl alcohol lead to a sharp increase in the rate of decomposition of [C3H5PdCl]2. In this case the amount of propylene formed is doubled and comprises one mole per C3H5PdCl group. Propylene is formed from theπ-allyl group, but not from allyl alcohol.

  5. 5.

    In an atmosphere of oxygen there is an inhibition of the decomposition of [C3H5PdCl]2. In this case the decomposition product is a compound of palladium (II).
